Its scheme was to first use its own soul to take over Lin Yifan's body, then to stage a murder where Qingqing, outside the cave, would hear Lin Yifan seemingly attacking and killing it, thus misleading Qingqing. Next, impersonating the person who had taken over Lin Yifan's body, it would pretend to be severely injured, struggling to crawl to the cave entrance, and seek Qingqing's help.
The cave entrance was well-lit, so Qingqing outside should be able to see Lin Yifan covered in wounds. All it needed was for Qingqing to rush into the cave, and it would instantly create a Boundary Wall, trapping Qingqing inside the cave before killing her.
This was its complete strategy, a plan guaranteed to make Qingqing enter the cave one hundred percent.
At that moment, it revealed a sinister smile, staring at Lin Yifan, who lay on the ground motionless, barely alive.
